Comments about LuLu by Objective-See as an Alternative to Little Snitch
I've used Little Snitch for many years. However, after buying a new Mac I was faced with buying licences for a whole bunch of apps I had paid for several times in the past. Given this unwanted additional expense and the fact that I really don't need all the extra features of the later versions of Little Snitch, I decided to try alternatives. LuLu absolutely fits the bill for the purpose of stopping apps phoning home without your permission.
Free (Libre) Software is and will be always best for the humanity :)
